The Meteor Falls is a unique cave with specific looks. It is originally entered just to battle Team Magma/Team Aqua, but is later fully explorable by utilising Waterfall. It has several paths and a couple of trainers to encounter.

Move TutorAfter completing the Delta Episode, when you return to Meteor Falls, you will find Zinnia\s grandmother right in the middle of the first floor. Speak to her, and she says she'll be happy to teach your Rayquaza the special move, Dragon Ascent, if it has previously forgotten it. Rayquaza needs to know Dragon Ascent to Mega Evolve.
